RS-232C Switch Settings
The DIP switches are located on the printed circuit board and are accessed from the bottom
of the printer. You do not need to remove any covers to change the DIP switches.
The DIP switches are used to set the RS-232C parameters and the Data Error and Data
Buffer options as shown. These parameters must match those of the host computer in order
for the host computer and the printer to communicate.
Caution: The switches can also be used for setting other functions and tests. Be careful
when setting the switches for the RS-232C settings that you do not accidentally change the
settings for the other functions and tests. See “Level 1 Diagnostics” in chapter 4 for more
information.
Use a paper clip or other pointed object to set the switches.
Note: The operator panel may differ depending on the model. To turn the printer on or
off, (on-line or off-line), use a paper clip or other pointed object to depress the plunger (in
place of the On Line button) on models with that item.
1. Press the On Line button (or plunger) to put the printer off-line.
2. Turn the printer over and set the switches to the desired settings shown in the table.
Switch 1 must be set to Off when setting switches for the RS-232C settings. This puts
the printer in the on-line mode to communicate with the host computer.
Caution: Do not set DIP switch 1 to On. Setting switch 1 to On puts the printer in level 1
diagnostics (setup) mode where other functions and tests can be changed.
